Ingredients
Scale
Cake
- 1¾ cup all-purpose flour
- 1 cup white sugar
- 1 cup light brown sugar
- ¾ cup dark cocoa powder
- 1½ tsp baking soda
- ¾ tsp salt
- â…” cup cooking oil
- ½ cup unsalted butter, melted
- 2 large eggs
- 2 tsp vanilla extract
- 1 cup buttermilk
- 1 cup hot water or coffee
Frosting
- 1 cup unsalted butter, softened
- 2 cup powdered sugar
- ½ cup cocoa powder
- ¼ cup heavy cream
- 1 tsp vanilla extract
- Pinch of salt
Instructions
- Preheat and Prepare Pans: Preheat your oven to 350°F (175°C). Grease and line three 9-inch round cake pans with parchment paper to ensure cakes do not stick.
- Mix Dry Ingredients: In a large bowl, whisk together the all-purpose flour, white sugar, light brown sugar, dark cocoa powder, baking soda, and salt until evenly combined.
- Add Fats: Stir in the cooking oil and melted unsalted butter into the dry ingredients until the mixture looks crumbly and combined.
- Incorporate Eggs and Vanilla: Beat the large eggs and vanilla extract into the batter, mixing thoroughly to combine everything evenly.
- Add Buttermilk: Slowly pour in the buttermilk while mixing gently to maintain a smooth batter without overmixing.
- Combine with Hot Liquid: Add the hot water or coffee gradually and mix until the batter is smooth and thin. The hot liquid helps to bloom the cocoa for a deeper chocolate flavor.
- Divide and Bake: Evenly distribute the batter among the prepared pans. Bake in the preheated oven for 22–25 minutes or until a toothpick inserted in the center comes out clean.
- Cool Cakes: Let the cakes cool in their pans for about 10 minutes, then remove them and transfer onto wire racks to cool completely before frosting.
- Prepare Frosting: Beat the softened butter until creamy. Gradually add the cocoa powder, powdered sugar, heavy cream, vanilla extract, and pinch of salt. Continue beating until smooth and fluffy.
- Assemble and Frost: Place the first cooled cake layer on a serving plate. Spread a generous amount of frosting on top, then repeat with remaining layers. Use the remaining frosting to cover the top and sides of the cake. Decorate as desired.
- Storage Instructions: Store the cake at room temperature covered lightly for 1–2 days. For longer storage, keep the frosted cake in an airtight container in the refrigerator for up to 5 days.
- Freezing Tips: Wrap unfrosted cake layers tightly in plastic wrap and aluminum foil and freeze for up to 2 months. Thaw completely at room temperature before frosting and serving.
Notes
- Using coffee instead of hot water intensifies the chocolate flavor without making the cake taste like coffee.
- Make sure butter is softened, not melted, for the frosting to achieve the best creamy texture.
- Ensure the cake layers are completely cool before frosting to prevent melting.
- For a richer taste, sift cocoa powder and powdered sugar before adding to the frosting to avoid lumps.
- If you prefer less sweet frosting, reduce powdered sugar slightly, keeping consistency in mind.
- Room temperature eggs and buttermilk help the batter combine more evenly for a better texture.
